Passenger's Air Mix Control Motor Test

Special Tools Required 

Backprobe Set 07SAZ-001000A (2)

1. Disconnect the 7P connector from the driver's air mix control motor
   NOTE: Incorrectly applying power and ground to the passenger's air mix control motor will damage it Follow the instructions carefully
2. Connect battery power to terminal No 1 of the passenger's air mix control motor, and ground terminal No 2, the passenger's air mix control motor should run, and stop at Max Cool If it doesn't, reverse the connections, the passenger's air mix control motor should run, and stop at Max Hot When the passenger's air mix control motor stops running, disconnect battery power immediately

3. If the passenger's air mix control motor did not run in step 2, remove it, then check the passenger's air mix control linkage and door for smooth movement
   • If the linkage and door move smoothly, replace the passenger's air mix control motor (see PASSENGER'S AIR MIX CONTROL MOTOR REPLACEMENT )
   • If the linkage or door sticks or binds, repair them as needed
   • If the passenger's air mix control motor runs smoothly, go to step 4
4. Measure the resistance between terminals No 5 and No 7 of the passenger's air mix control motor It should be between 4.2 and 7.8 kΩ
5. Reconnect the air mix control motor 7P connector, then turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
6. Using the backprobe set, measure the voltage between terminals No 3 and No 5

   Max Cool About 1.0 V 

   Max Hot About 4.0 V 

7. If either the resistance or the voltage readings are not as specified, replace the passenger's air mix control motor (see PASSENGER'S AIR MIX CONTROL MOTOR REPLACEMENT )
